WebTo sort an array in-place, use the "bang" version of the sort function: julia> a = [ 2, 3, 1]; julia> sort! ( a); julia> a 3 -element Array {Int64, 1 }: 1 2 3. Instead of directly sorting an array, you can compute a permutation of the array's indices that puts the array into sorted order: julia> v = randn (5) 5-element Array {Float64,1}: 0. ... Web8.25 ATAN2 — Arctangent function Description: ATAN2(Y, X) computes the principal value of the argument function of the complex number X + i Y. This function can be used to transform from Cartesian into polar coordinates and allows to determine the angle in the correct quadrant.
